Mercedes Benz gearbox TCU VGS2 on bench coding and programming done with Autel MaxiIM IM608 easily.
Found donor and renewed in seconds working perfectly.
it’s easy 4 steps
1. renew donor
2. copy data from old and backup coding
3. rewrite data and during restoring coding you vin number is selected of the old VGS after that u can write vin manually (and if you can’t read the old VGS you can use EIS data and then code and program online)
4. after fitting it back activite it and readaptation (notice without readaptation of gear range sensors you won’t be able to move or engage any gear)
Follow the wiring diagram below
Make sure you have the resistor that bridges 1 and 2 of can cl and Ch. Don’t use GBox it will delay.
Use Autel aac001 cable
